Liner Yellow 4m 1,2_1,6mm

The Yellow PVC Dam Liner is a premium, heavy-duty flexible membrane engineered for the demanding South African agricultural and civil engineering sectors. Available in a versatile 4-meter width and a robust thickness range of 1.2mm to 1.6mm, it is the primary choice for users who require a high-visibility lining solution. The distinct yellow color is not only an aesthetic choice but serves as a functional safety and inspection feature, making it easy to identify the water level and detect any structural debris or mechanical damage against the bright background.

Key Performance Features

• Industrial Rip-Stop Durability: Manufactured from high-tenacity PVC (Polyvinyl Chloride) that offers exceptional puncture and tear resistance, essential for rocky South African soil conditions.
• UV-Stabilized Formulation: Specially treated to withstand the intense African sun, preventing the material from becoming brittle or cracking over prolonged exposure.
• 1.2mm - 1.6mm Calibrated Thickness: Provides a significant barrier against root penetration and hydrostatic pressure, making it suitable for deeper water features and reservoirs.
• High-Visibility Safety Profile: The bright yellow finish improves underwater visibility, which is a critical safety factor for livestock troughs and public water features.

Ideal Applications

• Livestock Watering Holes: Provides a hygienic, easy-to-clean surface for cattle and sheep troughs, preventing the "muddying" of water sources.
• Agricultural Reservoirs: An efficient solution for lining irrigation dams to prevent water seepage and soil erosion.
• Aquaculture & Fish Farming: The non-toxic, food-grade PVC ensures a safe environment for fish while making it easy to monitor stock against the yellow backdrop.
• Industrial Spill Containment: Used as a heavy-duty bund liner for the temporary or permanent containment of non-corrosive liquids and runoff.

Product Benefits

• Pliable & Easy to Install: Despite its thickness, the material remains flexible enough to conform to irregular ground contours and corners during installation.
• Heat-Weldable Seams: Can be easily joined or repaired using industrial hot-air welding equipment, ensuring a 100% watertight seal over large surface areas.
• Algae-Resistant Surface: The smooth finish inhibits the rapid growth of algae, simplifying the maintenance and cleaning of the liner.

Pro Tip: Before laying your 4m liner, ensure the ground is "blinded" with a layer of fine sand or a non-woven geotextile underlay. This protects the 1.2mm–1.6mm membrane from sharp stones or roots that could cause "stress-points" once the weight of the water is applied. For the longest lifespan, try to keep the top edges of the liner covered with soil or rock to minimize direct UV contact on the anchor points.
